Hello,
I have a dilemma,

In VBS, I have a variable that reads a text input:

strObj = "Text/Text2/Text3"

I need to edit strObj so it will say only "Text/Text2" (basically discard everything after the 2nd "/" including)

Any advise?

Try this:
Option Explicit

Dim strObj, iPos

strObj = "Text/Text2/Text3"

iPos = InStr(strObj, "/")
If iPos > 0 Then
	iPos = InStr(iPos + 1, strObj, "/")
	If iPos > 0 Then
		strObj = Left(strObj, iPos - 1)
	End If
End If

MsgBox strObj

Hi, I just wrote this little function, which should work for you.  It returns the position of the specified instance of a character.

Regards,

Rob,

strObj =   "Text/Text2/Text3"

intChr = FindChrPos(strObj, "/", 2)

WScript.Echo intChr
WScript.echo Left(strObj, intChr - 1)

Function FindChrPos(strTheString, strTheChr, intInstance)
	intStart = 1
	For intNum = 1 To intInstance
		intFound = InStr(intStart, strTheString, strTheChr, vbTextCompare)
		intStart = intFound + 1
		If intStart > Len(strTheString) Then Exit For
	Next
	If intNum < intInstance Then intFound = 0
	FindChrPos = intFound
End Function

Here's a fairly simple approach.

arrTemp = Split(strObj, "/")
strObj = arrTemp(0) & "/" & arrTemp(1)

strObj = "Text/Text2/Text3"

Not griping, you are certainly free to select any working solution as you see fit.  Just want to understand if I missed anything, what made http:#a39163344 such an inferior solution for you, seems pretty compact and effective?  Or was it just because it wasn't first on the scene?

I agree. I did the same thing as @billprew - we posted just about the same time.  The only difference is I made a function so you can call the function anywhere in the code multiple times with one line.

There are always many ways to the same visual outcome though.
